JOHN W. FAIRBANKS, OF MARION, OHIO.

DRAFTIN G-TAB LE Application filed June 26, 1908.

Be it known that 1, JOHN W. FAIRBANKS, a citizen of the United States,residing at Marion, in the county of Marion and State of Ohio, haveinvented a new and useful Draft- -ng-T able, of which the following is aspecification.

This invention relates to drawing boards or tables and has for itsobject to provide a drawing board having an auxiliary board slidablymounted thereon and adapted to support a tracing, blue print or copy tobe used as a reference by the draftsman, said auxiliary board alsoforming a tray for the reception of drawing instruments and the like.

A further object of the invention is to provide a drawing board havingoppositely disposed guides secured thereto and spaced from the uppersurface of the board to permit the use of aT square or ruler, therebeing clips secured to the auxiliary board or tray and arranged to bearagainst the guides for imiting the longitudinal and vertical move- Astill further object of the invention is generally to improve this classof devices so as to increase their utility, durability and efficiency.

Further objects and advantages will appear in the following description,it being understood that various changes in form, proportions and minordetails of construction may be resorted to within the scope of theappended claims.

In the accompanying drawings forming a part of this specification:Figure 1 is a perspective view of a drawing board provided with anattachment constructed in accordance with my invention. Fig. 2 is atransverse sectional view of the same. Fig. 8 is a side elevation.

Similar numerals of reference indicate corresponding parts in all of thefigures of the drawings.

The improved device forming the subject matter of the present inventioncomprises a stationary board or table 5 preferably rectangular in shape,as shown, and having its lower surface reinforced and strengthened byspaced transverse cleats 6.

Secured to the upper surface of the board or table 5 are oppositelydisposed longitudinal strips 7 which form guides for an auxiliary boardor tray 8. The fixed ends of the strips 7 are spaced from the uppersurface of l Specification of Letters Patent.

Serial No. 140,539.

the board or table 5 by blocks 9 to form oppositely disposedlongitudinal slots 10 so as to permit the use of an ordinary "i" squareor ruler indicated at 11.

The free ends of the guides or strips '7 are extended longitudinallybeyond the adja cent edge of the board 5 to form supports 12 for thetray 8 when the latter is in the position shown in Fig. 1 of thedrawings, there being guide strips 13 secured to the lower face of theboard 8 and adapted to bear against the inner faces of the longitudinalstrips 7 to assist in guiding the board 8 when he latter is moved acrossthe face of the board or table 5.

The sliding section or board 8 is adapted to receive a tracing, drawingor blue print, indicated at 14, so that the latter may be supported in aconvenient position and used as a reference by the draftsman when makingplans, drawings and the like. One longitudinal e lge of the siding board8 is provided with a vertically disposed flange 15, which latter forms alinger piece for moving the section 8 to operative and inoperativeposition and also serves to prevent accidental displacement of drawininstruments and the like when the movable board 8 is used as a tray orsupport for said instruments.

Secured to the lower lon itudinal edges of the guide strips 13 are clipsor plates 16 which extend beneath the strips 7 and serve to preventvertical and tilting movem nt of the movable section 8, and byengagement with the adjacent blocks 9 also serve to limit thelongitudinal movement of said movable board.

When the draftsman desires to examine a copy or tracing on the movableboard 8, said board is moved to a position above the board 5 by exertinga longitudinal pull on the finger piece or ledge 15, the movable board 8being returned to the position shown in Fig. 1 of the drawing, after thecopy thereon has been examined so as not to interfere with the movementsof the draftsman when executing the work on the board 5.

It will here be noted that by spacing the longitudinal strips 7 from theupper surface of the table the '5' square or ruler may be moved to anyposition on the upper surface of the table 5, while the movable board ortray 8 forms a housing or protection for the drawing on the board 5 whensaid tray is adjusted to the limit of its forward movement.

The attachment may be made in different sizes and shapes and used inconnection with drawing boards, stands or tables.

From the foregoing descri tion it Will be seen that there is provide anextremely simple, inexpensive and efiicient device admi ab y a pte forthe inmen f the ends in view.

Having thus described the invention what is claimed is:

1. A drawing board having oppositely disposed guides secured thereto andspaced from the upper surface of the board, and a tray slidably mountedon the guides and movable to a position beyond said board.

2. A drawing board having longitudinally disposed guides secured theretoand spaced from the upper surface of the board, a tray slidably mountedon the guides, and means carried by the tray and extending beneath theguides for limiting the longitudinal and vertical movement of said tray.

3. A drawing board having oppositely disposed longitudinal guidessecured thereto and spaced from the upper surface oi the board to formoppositely disposed slots, a tray slidably mounted on the guides andprovided with strips adapted to bear against said guides, and platessecured to the tray and extending beneath the longitudinal guides atsaid slots for preventing tilting movement of said tray.

4. A drawing board having longitudinal guides secured thereto and spacedfrom the upper surface of the board to form oppositely disposed slots, atray slidably mounted on the guides and adapted to receive a copy, onelongitudinal edge of the tray being provided with a vertically disposedledge, clips carried by the tray and extending beneath the guides atsaid slots, said tray being movable to a position above the drawingboard.

5. A drawing board including a body portion, spacing blocks secured tothe upper surface of the body portion, longitudinal guides secured tothe blocks and spaced from the upper surface of the board to formtransversely alined slots, the free ends of the strips being extendedlongitudinally beyond the adjacent end of the body portion to formsupports, a tray slidably mounted on the strips and provided withcorresponding strips co-acting with the longitudinal strips, one edge ofthe tray being provided with a vertically disposed ledge constituting afinger piece, and clips carried by the tray and extending beneath thelongitudinal strips for engagement with the adjacent spacing blocksthereby to limit the longitudinal movementof the tray.

In testimony that I claim the foregoing as my own, I have hereto affixedmy signature in the presence of two witnesses.

JOHN W. FAIRBANKS.
